Hmmm....just guessing here. I would say, since both balls are there, the provisional is abandoned, one must be the original, so the original is not lost. The question becomes, which is the original ball and which is the provisional (which must be abandoned because the original one must be there since there's two of them). I would think there is some penalty if you can't determine which is which. If you accidentally play the provisional, you run the consequence of playing with the wrong ball. Still haven't figured out what the outcome is.
